Singing Hot And Cool: The Polyvagal Theory And Vocal Pedagogy
Thursday 17th June 2021, 5:00 PM - 7:00 PM (London Time)
The vagus nerve is closely involved with both the larynx and the autonomic nervous system (ANS). The polyvagal theory details the remarkable role of this nerve bundle in the evolution of voice and speech communication, and affirms the power of the voice as an instantaneous transmitter of ANS status, both in daily life communication and between artist and audience. Finally, parallels emerge between the vagus nerve’s contributions to psycho-physiological resilience (the ability to be aroused and calm at the same time) and artists’ descriptions of stage presence. Crosslinks between neurological evidence and the experience of performing arts will support suggestions for vocal pedagogy.
REVIEW OF TERMINOLOGY
- Structures of interest: cranial nerve X (vagus) and its brainstem nucleii
- Functions of interest: autonomic versus sensory-motor
- Autonomic (ANS) components: sympathetic (“hot”) and parasympathetic (“cool”)
THE POLYVAGAL THEORY OF SOCIAL COMMUNICATION
- Characteristics of the vagus nerve in animals and humans
- How “hot and cool” ANS regulation makes speech and singing possible
THE POLYVAGAL VOICE
- Muscle controls in the vagus nerve: larynx and more
- Voice as a carrier of ANS signals, in daily life and performance
THE POLYVAGAL THEORY ONSTAGE
- How performers describe the inner state onstage
- Is “very hot and very cool” the ANS recipe for stage presence?
RECOMMENDATIONS FOR ARTS TEACHERS
- ANS regulation as a pedagogical goal
- The importance of training ensembles
- Suggestions for warm-ups, cool-downs, and performance anxiety
- The well-regulated teacher

Unclenching the Jaw: Options from the Physio Lens
Walt Fritz
“Jaw tension” is one of many potential problems facing the singer, and can cause a direct negative impact on the performance in both direct and indirect ways. The underlying cause of jaw issues is attributed to numerous factors (technique, posture, strength, range of motion, etc.), making it often difficult to identify common denominators. Join Walt Fritz as he examines the evidence supporting stretching, strengthening, and manual therapy interventions to address jaw-related concerns in vocal performers, taking into account their unique needs.

Certificate in Foundations of Vocology with Adam Roberts
Adam Roberts
This 30-hour Vocology Cohort Intensive provides a comprehensive overview of basic vocal anatomy, physiology, and theories of voice production & perception, fundamentals of vocal health, pathology, evaluation, performance, and habilitation of the speaking and singing voice, and a survey of research, resources, and professional opportunities. Each week, advanced students contribute to cohort-centred learning with additional resources, discussion facilitation, and critical analysis. The course assessment will also be useful for those who wish to prepare for the PAVA recognised designation.
